    Faith based interventions have been underutilized to improve water, sanitation and hygiene status and offers promise to promote behaviour in the community. Prior to delivering a faith based WASH intervention, we conducted a survey among the neighbouring households of eight Bangladeshi Islamic schools and associated mosques. We randomly selected 192 families from where any male attend mosque and interviewed adult women from that family. At baseline, almost all households used improved water sources and improved toilets. However, toilet cleanliness was poor. Faecal matter was disposed into the environment after emptying the pit/septic tank. Defecation and disposal among children <3years mostly occurred directly in the open which should be improved using behaviour change recommendations. Presence of hand washing agent in the hand washing place was low. Islamic faith based intervention should be designed and delivered in way that can promote hand washing, safe sanitation practices and safe disposal of child faeces

    BACKGROUND: Diabetes in pregnancy is common in South Asians, especially those from low-income backgrounds, and leads to short-term morbidity and longer-term metabolic programming in mother and offspring. We sought to understand the multiple influences on behaviour (hence risks to metabolic health) of South Asian mothers and their unborn child, theorise how these influences interact and build over time, and inform the design of culturally congruent, multi-level interventions. METHODS: Our sample for this qualitative study was 45 women of Bangladeshi, Indian, Sri Lankan, or Pakistani origin aged 21-45 years with a history of diabetes in pregnancy, recruited from diabetes and antenatal services in two deprived London boroughs. Overall, 17 women shared their experiences of diabetes, pregnancy, and health services in group discussions and 28 women gave individual narrative interviews, facilitated by multilingual researchers, audiotaped, translated, and transcribed. Data were analysed using the constant comparative method, drawing on sociological and narrative theories. RESULTS: Key storylines (over-arching narratives) recurred across all ethnic groups studied. Short-term storylines depicted the experience of diabetic pregnancy as stressful, difficult to control, and associated with negative symptoms, especially tiredness. Taking exercise and restricting diet often worsened these symptoms and conflicted with advice from relatives and peers. Many women believed that exercise in pregnancy would damage the fetus and drain the mother's strength, and that eating would be strength-giving for mother and fetus. These short-term storylines were nested within medium-term storylines about family life, especially the cultural, practical, and material constraints of the traditional South Asian wife and mother role and past experiences of illness and healthcare, and within longer-term storylines about genetic, cultural, and material heritage - including migration, acculturation, and family memories of food insecurity. While peer advice was familiar, meaningful, and morally resonant, health education advice from clinicians was usually unfamiliar and devoid of cultural meaning. CONCLUSIONS: 'Behaviour change' interventions aimed at preventing and managing diabetes in South Asian women before and during pregnancy are likely to be ineffective if delivered in a socio-cultural vacuum. Individual education should be supplemented with community-level interventions to address the socio-material constraints and cultural frames within which behavioural 'choices' are made

    Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent of COVID -19, is constantly evolving, requiring continuous genomic surveillance. In this study, we used whole-genome sequencing to investigate the genetic epidemiology of SARS-CoV-2 in Bangladesh, with particular emphasis on identifying dominant variants and associated mutations. We used high-throughput next-generation sequencing (NGS) to obtain DNA sequences from COVID-19 patient samples and compared these sequences to the Wuhan SARS-CoV-2 reference genome using the Global Initiative for Sharing All Influenza Data (GISAID). Our phylogenetic and mutational analyzes revealed that the majority (88%) of the samples belonged to the pangolin lineage B.1.1.25, whereas the remaining 11% were assigned to the parental lineage B.1.1. Two main mutations, D614G and P681R, were identified in the spike protein sequences of the samples. The D614G mutation, which is the most common, decreases S1 domain flexibility, whereas the P681R mutation may increase the severity of viral infections by increasing the binding affinity between the spike protein and the ACE2 receptor. We employed molecular modeling techniques, including protein modeling, molecular docking, and quantum mechanics/molecular mechanics (QM/MM) geometry optimization, to build and validate three-dimensional models of the S_D614G-ACE2 and S_P681R-ACE2 complexes from the predominant strains. The description of the binding mode and intermolecular contacts of the referenced systems suggests that the P681R mutation may be associated with increased viral pathogenicity in Bangladeshi patients due to enhanced electrostatic interactions between the mutant spike protein and the human ACE2 receptor, underscoring the importance of continuous genomic surveillance in the fight against COVID -19. Finally, the binding profile of the S_D614G-ACE2 and S_P681R-ACE2 complexes offer valuable insights to deeply understand the binding site characteristics that could help to develop antiviral therapeutics that inhibit protein–protein interactions between SARS-CoV-2 spike protein and human ACE2 receptor

    Understanding how immigrant entrepreneurs view business opportunity formation through ethnicity

    Get PDF
    Given that international research is now consistently showing higher rates of entrepreneurial activity from immigrants above native people, research regarding our understanding of how immigrant entrepreneurs view business opportunity formation remains underdeveloped. Based upon a review of the literature, this chapter examines how ethnicity relates to business opportunity formation through constant interactions. It also introduces the Visual Mixed Embeddedness Framework as an empirical lens for understanding the differences in the business opportunity formation process models between immigrant and native entrepreneurs. By explaining how factors and traits from both home and host countries impact upon the immigrant entrepreneurial business activity process, the framework clearly identifies how the concept of ethnicity influences immigrant entrepreneurial opportunity formation activities in different ways. The framework contributes to existing knowledge by offering a novel method for examining the influence on business opportunity formation of ethnicity, the role of home and host countries and variations between immigrant and native entrepreneurs

    <p>Abstract</p> <p>Background</p> <p>Our previous studies showed that ZBTB20, a new BTB/POZ-domain gene, could negatively regulate α feto-protein and other liver-specific genes, concerning such as bio-transformation, glucose metabolism and the regulation of the somatotropic hormonal axis. The aim of this study is to determine the potential clinical implications of ZBTB20 in hepatocellular carcinoma (HCC).</p> <p>Methods</p> <p>Quantitative real-time RT-PCR and Western blot analyses were used to detect expression levels of ZBTB20 in 50 paired HCC tumorous and nontumorous tissues and in 20 normal liver tissues. Moreover, expression of ZBTB20 was assessed by immunohistochemistry of paired tumor and peritumoral liver tissue from 102 patients who had undergone hepatectomy for histologically proven HCC. And its relationship with clinicopathological parameters and prognosis was investigated.</p> <p>Results</p> <p>Both messenger RNA and protein expression levels of ZBTB20 were elevated significantly in HCC tissues compared with the paired non-tumor tissues and normal liver tissues. Overexpressed ZBTB20 protein in HCC was significantly associated with vein invasion (<it>P </it>= 0.016). Importantly, the recurrence or metastasis rates of HCCs with higher ZBTB20 expression were markedly greater than those of HCCs with lower expression (<it>P </it>= 0.003, <it>P </it>= 0.00015, respectively). Univariate and multivariate analyses revealed that ZBTB20 overexpression was an independent prognostic factor for HCC. The disease-free survival period and over-all survival period in patients with overexpressed ZBTB20 in HCC was significantly reduced.</p> <p>Conclusions</p> <p>The expression of ZBTB20 is increased in HCC and associated with poor prognosis in patients with HCC, implicating ZBTB20 as a candidate prognostic marker in HCC.</p

    An experiment was conducted to assess the effect of introgressing autosomal recessive dwarf gene (adw) from Bangladeshi indigenous (deshi) dwarf (DD) chicken to Rhode Island Red (RIR), White Leghorn (WLH) and Fayoumi (FO) on body weight and egg production. Deshi normal (DN), DD, RIR, WLH and FO were used in crossings to produce 8 genotypes; RIR, WLH, FO, DN, DD, RIR x DD, WLH x DD and FO x DD. At 19 weeks of age, for separation of crossbreds into normal and dwarf on the basis of shank length, altogether gave 11 genetic groups; RIR, WLH, FO, DN, DD, RIR x DD normal, WLH x DD normal, FO x DD normal, RIR x DD dwarf, WLH x DD dwarf and FO x DD dwarf. At 19 weeks of age, 154 pullets; 14 from each genetic group were individually caged up to 42 weeks of age to compare egg production performance. Introgression of adw gene significantly reduced mature body weight and feed intake and adw pullets utilized feed more efficiently into egg mass in comparison with their normal size counterparts. Conservation and improvement of deshi adw chicken is suggested for their future use in breeding for egg production

    Bacillus thuringiensis (or Bt) is a commonly used as a pesticide. B. thuringiensis is a naturally-occurring soil bacterium, also occurs naturally in the gut of caterpillars of various types of moths and butterflies, as well as on the dark surface of plants. The xylanase producing bacterial strains were isolated from dump soil. The strains were isolated on xylan agar media and screening was carried out by xylanolysis method. To test the sensitivity of the isolates, ten different antibiotics were used. The strains were tested for resistance to doxycyclin, erythromycin, chloramphenical, cephallaxin, kanamycin, ampicillin, steptomycin, vancomycin, amoxycillin and neomycin. The strains showed sensitive to doxycyclin, erythromycin, chloramphenical, cephallaxin, kanamycin, ampicillin, steptomycin and vancomycin and also showed resistance to amoxycillin and neomycin, when tested by disc diffusion method on nutrient agar plate confirmed by antibiotic spread plate method. The inhibitory effect of B. thuringiensis strains against the test bacteria Bacillus subtilis, Sarcina lutca, Shigella dysenteriae, Shigella sonnei and Pseudomonus aeruginosa examined. It was found that, B. thuringiensis S1, B. thuringiensis S2 and B. thuringiensis S3 strains showed an inhibitory effect on all of the test bacteria

    The pattern and problem of poultry consumption by the rural and urban families of Fulbaria upazilla were studied. Data were collected through interview schedule from 100 respondents (50 from rural area and 50 from urban area). Problem confrontation index (PCI) in urban area 27 to 143 against the possible range of 0 to 150 and in rural area 33 to 138 against the possible 0 to 150. Overall area PCI was 60 to 281 against the possible range of 0 to 300. Nonavailability of day old chicks, lack of optimum amount of feed, unbalanced diets and fluctuating prices of eggs and meat were the acute problems hampered the consumption of poultry. The average farm size in urban and rural areas was 167.84 and 233.94 decimal. Livestock population consisted of 80% poultry and 20% large animal. Poultry contributed 4% of the total income in the rural area and 3% in the urban area. Rural people have less knowledge on health and nutrition than that of urban people. Poultry consumption in both rural and urban area is certainly very low. A positive correlation of age with poultry consumption implies that per capita poultry consumption is higher for older people. Reverse case is expected to build a healthy society. From correlations it can be concluded that in urban area increased farm size, increased livestock population, increased income, better knowledge on health and nutrition and decreased family size should increase per capita poultry consumption. Correlations also indicate that decreased family size and better knowledge on health and nutrition could minimize problems of poultry consumption. In rural area correlations computed impress that increased literacy, increased farm size, increased livestock population, increased income and better knowledge on health and nutrition should increase per capita poultry consumption. Whereas, increased income could remove problems of poultry consumption
